COVER-CIJOSURE FDR SHEET-METAL VESSELS.

Application tiled Dctober 23, 1907. Serial No. 398,749.

Be it known that I, CHARLES STOLLBERG, a

States, residing in Toin the county of Lucas and State of Ohio, have invented anew and useful Improvement in Cover-Closures for Sheet- Metal Vessels, of which the following is a specification.

My invention relates to closures for sheet metal pails or vessels having inside fitting removable slip covers. such as are used for containing candy, lard. grease or other articles and which are o large size or capacity and require a strong and secure fastening means for the covers, that atv the same time may be readily removed and easily and conveniently applied.

The object ot my invention is to provide a strong, simple and efficient means for securing slip covers on sheet metal pails or vessels which may be easily and conveniently clip before it is applied. Fig. 7 is a det-ail applied to enable the vessel to be readily opened and which will safely, tightly and securelyT hold the cover on the vessel whatever may be its size or diameter and which will obviate the necessity of providing the cover or the body of the vessel with clenching lips or ears such as have heretofore been -ordinarily secured to either the cover or the pail body either byinaking the saine integrall therewith or by solde-ring or riveting them thereto.

My invention consists in the means I ein- `ploy to practically accomplish this object or result as herein shown and described 'and more particularly specied in the claims'.

In the accompanying drawing forming a part of this specification. Figure 1 is a side elevation of a sheet metal pail or vessel embodying my invention, partly in vertical section. Fig. 2 is a detail plan view of a short section of the rim of the pail with a cover holding clip applied. Fig. 3 is a similar detail plan view showing the cover holding clip removed. Fig. 4 is a detail sectional view showing the cover' holding clip in position ready to be applied. Fig. 5 is a detail sectional view showing the clip applied `and the pincers for applying saine. Fig. 6 is a. detail perspective view of the cover holding sectional view Ashowing the cover holding clip partially removed.

In the drawing,A represents a. sheet metal `knife blade o r -down of the `flange ,bi snugly against pail or vessel, such, for example, as is coingrease or other heavy bulky articles.

body a of the pail has an external roll or,`

shoulder al at its upper or mouth end, ordi-*1 preferably inclosing a strengthennarily or ing wire C.

B is the inside fitting countersunk cover of the pail. the saine having a deep friction seat wall 7) terminating in an outwardlyprojecting curved flange b1 which fits on top ot the external. roll c at the upper end of the pail body. the flange b1 preferably projecting slightly horizontally outward to an extent about equaling the diameter of t-he external roll al ot the pail body a.. f

D is a separate-piece, cover-holding, clip having' a segmental circular curved outer portion fitting andenibracing the external roll on the body of the vessel and a straight depending leg (Z1 iitting flat against the friction seat wall Z) of the countersunk cover B, said leg Z1 being provided at its lower end with a curved lip d2 to enable a screwdriver, other like instrument `to be inserted for prying oft or turning up the clip D, as illustrated in Fig. i'. Before the clip D is applied to the cover and pail, it has a straight horizontal upper portion d3 to Aenable the clip to be readily assembledl on the cover and pail, asillustrated in Fig. et, after which the clip is applied lto the cover and pail by means-ot' a pair of pincers F or other suitable tool, the'outer jaw]e of which has a curved recess f1 conforming to the curved outer-segment d of the clip D, and the other jaw f2 of which is provided with a flat tace f3 to tit snugly against the straight depending leg d1 o1 the clip. In

the act of applying the clip to the cover andv i pail by the pincers, the straight horizontal portion Z3 of the vclip 'is curved or bent snugly about the cover flange b1 and external roll a? of the body as shown in Figs. l. 2 and 5. This operation of tightening the clip on the cover is accomplished byclosing the pincers. and is attended with a bending projecting edge of thecover al on the body ot the vessel, and thus forining av locking bend or recess b2 in the cover flange which serves to slipping or moving or otherwise becoming loosened. 7

the external 'roll' prevent the clip from Theclip D maybe made of sheet steel or i otherI suitable metal.

In opening the vessel o r removing the cover, the cireularly curved portion of the clip which embraces the external lcircular A.roll on the upper end of the vessel permits the clip to readily turn 'as a pivot t about the circular roll to a limited extent without material binding to permit the depending leg of the clip to swing away from the upright countersunk Wall of the cover far enough to enable it to be firmly grasped y as a lever, and the requisite -force thus applied to spring the clip from the cover. This willbe readily understood from Figs. and

7 of the drawing, the former showing the Iclip its applied position and the latter .shoyvin'g' it "partially removed. -ettieient clips may thus be employed, and

Strong and at the samev time very easily 'and readily removed. y

'l claimtv .L A cover closure for sheet metal vessels,

'- comprising an external circula-r roll on the upper -end of the vessel body, a counters'unk cover fitting Within the vessel body and having a friction seat Wall provided With an externally projecting flange,4 and sep/:irate each pieceremovable cover holding clips having a circularly curved outer portion embracing the cover iange and vexternal roll of the-body, 4curved concentrieally therewith and adapted tol turn thereon asa pivot in the act of removal, and l'provided with a straight depending leg fitting snugly against the friction seat Wall of the countersu'nk cover,

and serving as a lever to turn the clip in removing the same,. the pivotal turning movement of the clip enabling its depending leg to swing avfay vfrom the adjacent Wall of the cover sufficiently to enable it to be grasped in the actof removal, substantially fas specified.

2. A cover closure for sheet metal vessels, comprising an external: circular roll on the upper end of the vessel body, a counter-sunk cover fitting Within the vessel body and having a friction seat Wall provided `with an 4externally projecting flange, and

separate piece removable cover holding clips, each having. a 'circularly curved outer portion embracing the cover iange and external roll of the body, curved concentrically there- `with and adapted to turn thereon as a pivot in the act of removal, and provided with a straight dependmg leg htting snugly against the friction seat Wall of the countersunk jacent wall of the cover sufficiently to enable it to be grasped in the act of removal substantially as specified. l'
